Please upgrade your tzdata dependency when possible

[Trevoke]

Hello,

Recently, a CVE (Common Vulnerability and Exposure) was created for hackney, one of the dependencies of tzdata - one of your dependencies.

Hackney is aware of this ( benoitc/hackney#751 ) and will create a release soon ( benoitc/hackney#753 (comment) ).

When the new tzdata release comes out, please create a new timex release incorporating this security update.

Thank you!
